In a shift control device for an automatic transmission capable of switching from a normal automatic shift control to a drive-downshift forcible termination control when a time rate of change in transmission input speed is reduced to below a threshold value owing to a drop in transmission input torque during drive downshift from a higher gear position to a lower gear position with an accelerator pedal depressed, a drive-downshift forcible termination control section is provided. The drive-downshift forcible termination section executes the drive-downshift forcible termination control only when the time rate of change in transmission input speed is reduced to below a first predetermined threshold value and a value equivalent to the transmission input torque is reduced to below a second predetermined threshold value, to forcibly terminate the drive downshift. |
